The Cardinals signed former Raiders unrestricted free-agent LB Quentin Groves on Thursday, the team confirmed.
Groves will be entering his fifth season in the NFL. He spent the past two with the Raiders. In 2011, he played in all 16 games, with three starts, and recorded 24 tackles, two passes defensed and one forced fumble.
Groves played for the Jaguars from 2008-09. He has missed only one game in the past four seasons and has six passes defensed and two interceptions.
To make room on the roster, the Cardinals released undrafted free-agent WR Marc Wilson.
